2026-10-09 APP 2.0.0-beta48 has been released !
This is mainly a bug fix release for the reported bugs in beta47. In addition it has a significant User Interface performance improvement noticable when you need to process 1000s of images in APP.
2026-10-03 APP 2.0.0-beta47 has been released !
This is a very big release... many code optimizations/rewrites, many parts of APP are much faster and more precise, especially star analysis and registration are much faster ! Big mosaics will go much faster 🙂
And we introduce a new preview filter, which includes the new Adaptive Deep Sky Stretch and a General Levels Stretch, this has been long over due. The old preview filter (the panel on the right side to stretch and preview your data) has not been updated for a couple of years and it is a critical part of any APP session.
Adaptive Deep Sky Stretch or ADSS is a much more intuitive stretch algorithm. It is also color preserving (which is a great new addition in itself ! ) which means that the highlights are no longer bleached, color is maintained from the linear data while stretching. You can simply stretch your data using the sky background level and signal width sliders which work much easier and more intuitive. You no longer need to fiddle with the old complicated sliders with zoom buttons. All the zoom buttons for the sliders are made redundant. And you can enter slider values in the slider value fields yourself. I will make a youtube video in the coming days to explain and fully introduce ADSS. Once the video is ready, it will be highlighted on the forum.
RGB Combine upgrade !. The RGB Combine Tool has been rewritten mostly. The tool is faster and easier to use and most importantly, the Luminance slider to inject a luminance channel or channels into the RGB composite is now working correctly. It no longer bleaches the RGB colors. Combined with the new ADSS preview, you will get much better and easier great composites with great color! I will also explain this in a new youtube video.
I find this very cumbersome...... If you have an image in the lower console and you want to use the 9) Tools on it for LP correction, or cropping, then every time the software makes you open it from a saved position.
PLEASE can it be amended so that you can actually work on the image that you have open. I think this would make life very much easier and less confusing.
Hi Sara,
Yes we can definitely improve here 😉
I need to give it some thought on how to do this most friendly.
I could either
- make a right mouse click menu that will start the tool from a selected file in the frame list or
- when you load a tool, including the batch tools, you are first presented with the question if you want to use the "unstretched data" from the image viewer/preview filter or load a new one.
I would prefer the second option I think, (and it will be the easiest to implement for now). With the second option, you can directly process your image with all tools using the result that you currently have in the image viewer. That should improve things considerably.

I think that the second option seems very good..... It's really frustrating to have the image there and open and instead you need to re-open it to work on it.
Maybe though you need to have an option to select which open file you want to use as you could have a few open (Different integrations, different processes etc)Â
Hi Sara,
I have enabled the second option now for the batch modify tool. It works nicely now.
I'll adjust the other tools as well 😉
Now I also think, that for these tools and also at the end of light integration, you want the result to be loaded directly to the screen, so you don't need to select it to verify it yourself. I'll make a seperate RFC for this.

Excellent - Will this be in the next APP release?
